“Broad is the way, that leadeth to destruction, and many there be which go in thereat  ...  Strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it” (Matthew 7:13-14).
People love to believe there is a heaven, but resent being told there is a hell.
Without any authority, many try to prove the nonexistence of hell, or they deny its endlessness. The only true authority, the Son of God who knew all about it, has spoken thus: “These shall go away into everlasting punishment: but the righteous into life eternal” (Matthew 25:46). “Be not afraid of them that kill the body, and after that have no more that they can do. But I will forewarn you whom ye shall fear: Fear Him, which after He hath killed hath power to cast into hell; yea, I say unto you, Fear Him” (Luke 12:4-5). “Into hell, into the fire that never shall be quenched: where their worm dieth not” (Mark 9:43-44). “There shall be weeping and gnashing of teeth” (Matthew 24:51). “If ye believe not that I am He, ye shall die in your sins.” “Whither I go, ye cannot come” (John 8:24, 21).
“It is appointed unto men once to die, but after this the judgment” (Hebrews 9:27). “The wicked shall be turned into hell” (Psalm 9:17).
The Son of God came down to earth and went to the cross to be made sin (2 Corinthians 5:21) and to bear our sins (1 Peter 2:24). The purpose was to save sinners from being “punished with everlasting destruction” (2 Thessalonians 1:9).
In the cross of Christ we see that “God is love,” but also that He is holy.
